Neoplasia Flashcards
Non-neoplastic normal tissue in a foreign location
Choristoma
Replacement of 1 adult cell type w/ another, often 2ndary to irritation and envt’l exposure
Metaplasia
Abnormal growth w/ loss of cellular orientation, shape and size
Dysplasia
Abnormal cells lacking differentiation
Anaplasia
Uncontrolled and excessive clonal proliferation of cells
Neoplasia
Fibrous tissue formation in response to neoplasm
Desmoplasia
Mutations that cause sustained activity of the genes
Proto-oncogenes
Mutations causing unregulated cell proliferation
Tumor suppressor genes
Non-neoplastic overgrowth of disorganized tissue indigenous to a particular site
Hamartoma
Neoplasia that has not invaded the BM; high NC ratio and clumped chromatin; tumor cells are monoclonal
In Situ Carcinoma
Neoplasia that invaded the BM using collagenases and hydrolases
Invasion
Accompanies neoplasia where tumor cells spread to distant sites; Dec cadherin, inc laminin and integrin receptors
Metastasis
Degree of cellular differentiation based on histo pattern
Tumor grade
Degree of local spread
